[SciPy-User] How to build simulation software like Simulink using SciPy?

[Stef Mientki]

or look at PyLab_Works
http://mientki.ruhosting.nl/data_www/pylab_works/pw_animations_screenshots.html

One of the tricks for closed loop with visual feedback,
is to perform more than 1 network calculations in one display loop.
So let's say 50 frames per second fr visulization, and 1000 calculations 
per second.

cheers,
Stef
